CISTERN FOR WATER-QLOSETS.

I Specification of Letters Patent.

Patented March 10, 1908.

Application filed. September 24, 1906. Serial No. 335.970.

To all whom it may concern:

Be it known that 1, JOHN R. HALL, a citizen of the United States, residing at Forest Grove, in the county of Washington and State of Oregon, have invented certain new and'useful Im rovements in Cisterns for Water-Closets, 0 which the following is a specification.

My invention pertains 'to improvements in cisterns for water-closets, more especially the valve-mechanism employed in connection therewith. f

It has for its objectprimarily to control the action of the inrushing water to the tank or cistern for relativel reducing the pressure thereof and its de 'very into said tank or cistern to render such action noiseless and carry out these ends in a simple, economic and efleotive manner.

Sald mvent1on consists of.cert a1n features or lnstrumentahtles substant1ally as hereinafter fully disclosed and specifically pointed out by,the claims.

In the accompanying drawing illustrating the preferred embodimentof my invention Figures 1 and 2 are sectional elevations there of showing the action of the parts previous to the filling of the tank 011 cistern and the action of such parts when the latter has been filled.

Fig. 3 is an enlarged detailed vertical section showing more particularly the sectional supply or delivery pipe for the tank or cistern.

ig. 4 is a like view, with arts broken away, showing more especially t .e float-valve actuated sleeve, together with the supply and cut-off valve for the cistern or tank. Figs. 5 and 6 are disassembled views of the manually actuated discharge valve and its cage or guide of the tank or cistern, respectively.

Figs. 7, 8, 9 and 10 are detailed vertical sections' of pipe-sections of the delivery or supply pipe for reducing pressure.

In the disclosure of my invention, Isuit ably provide the usual water-closet cistern or tank 1 with an inlet or supply pi e 2 passing up through the bottom of sai tank or cistern and having its upper portion curved downward as at a and terminating contiguous to said bottom. Said supply or delivery pipe 2 provides for lessening or reducing the pressure of the water entering the discharge end of the pipe and finally entering the cistern or tank, accordingly lessening the inrushing force of the Water, whereby the noise, usually attending this action thereof, is wholly over come, as is obvious. This vis effective as follows: A nozzle-equipped pipe-section 3 with its nozzle, say three-sixteenths' of an.

inch in diameter," may be applied to said supply-pipe 2 when the pressure of the water in the service pipe is from seventy-five to one hundred po 'nds to the square inch; or should the water pressure be from fifty to seventyfive pounds a like-equipped pipe-section 4; with its nozzle, say five-sixteenths of an inch in diameter I may be employed in lieu of the pipe-section 3 or should the water pressure be twenty-five poundsstill a like third pipesection 5 with its nozzle, say three-eighths of an inch in diameter, may take the place of the pipe-section 4; and when the-pressure is under twenty-five pounds the diameter of the pipe-section 6 for substituting any of the aforesaid pipesections is a half inch or the same as that of' the pipe 2 discharging directly into the tank or cistern. Said downward curved portion a of said pipe has a number of lateral Water-outlets b throu h which it discharges, as well as through its lower end or, terminal, into the cistern or tank, thus dividin up the discharge of the water under abate pressure and accordingly aiding in avoiding the noise caused by the releasing of the water under pressure and its delivery into the tank or cistern.

t rough apertures in a sleeve or slide 12 arranged upon the latter, said yoke being suitably held from displacement by nuts 13 screwed upon their ends, outside of, and againstsaid sleeve.

A supply and cut-off valve 14, arranged within the pipe 2 and flared at its lower or effective end, and which is adapted tobe seated upon and close an upward tapered seat or port 15 also arranged Within, and se-- cured vto the inner surface of said ipe, is secured centrally to, and carried by tlie yoke ll), and therefore capable of actuation by the float-valve 7 as is ap arent.

A suitable rnanualy operated valve 16,-

also arranged within the tank or cistern 1, is adapted to control the delivery of the Water from said cistern or tank to the closetbowl as required for flushing purposes. Said valve has its lower enlarged cylindric terminal 17 arranged to have movement within, and is guided by a corres )onding cage or guard 18 secured to the tan or cistern bottom around the discharge opening therein, said valve also having a tubular stem 19 fixed to, and opening into the part 17 thereof out through its upper "end thus serving, in addition, tor venting )urposes as well understood. A centrally ulcrunied lever 20, arranged upon a suitable support 21 in the top end of the tank 6r cistern 1 and suitably connected to the stem 19 of the valve 17 near its upper end, has attached to its outer end a dangling hand-hold equipped chain 22, or like suitable means, for ready grasping and actuation as in operating said valve as appreciated. 7

From the foregoing description of the con struction and operation of the aforesaid parts,

it is thought t at no further elaboration of esneso this matter is in order for the full understanding of my invention.

I claim 1. A device of the character described e1nloying a supply pipe, a fioat valve lever ulcrumed from said pipe, a sleeve slidingly arranged upon said pipe, a yoke or member arranged to slide with said sleeve and controlled by said float-valve lever, and a supply valve for controlling the inlet of the water to said pipe and itself controlled by said floatvalve lever said supply-valve being connected by said yoke to said sleeve.

2. A device of the character described, em' ploying a supply pipe equipped with a ported seat within, a downward flared valve engaging said seat, a sliding sleeve arranged u )on said pipe, a yoke or cross-bar conneete to said sleeve and )assing through opposite vertical slots in sai pipe and through said sleeve, said valve being connected to said yoke, a bracket secured to said pipe, a float-valve lever having its 'arin connected to said yoke and fulcrumed upon said bracket.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.

JOHN R. HALL.
